No he's right.
It's just that in 35 years of working on countless servers and desktops
from all different manufacturers I did encounter a single motherboard
one time that had a different pinout and needed the specific cable that
came with the board. Everything else in all those machines and buying
the cables separately from various sources not tied to any boards or
even manufacturer have all been interchangeable.

I don't think you understand. There used to be a peripheral "card" which
was just a short cable that plugged into the motherboard and led to a DB
25 on the back of the PC, then your parallel printer cable would just
plug into that. The printer connector on the back of the M100 is the
same as the one on the motherboards, so just get one of those adaptors
and remove the bracket for mounting on the PC, and you've got your
adaptor cable. Of course, I do like my Radio Shack original Model T to
centronics parallel printer cable.

Careful with those PC internal printer cables; like the DVI issue,
some are wired pin to pin and some wired for straight crimping.
And wasn't there a simple hack to reroute printer output to the
RS-232 port?

The device itself has a db25f plug to plug directly into the
back of most pcs, but the adapter from that to the 100 turns out
to be simple. Just one of those off the shelf generic pc
motherboard parallel port cables that go from the motherboard to
the case.

Although a null modem cable connecting the Model 100 serial
port to a PC
can handle some tasks, there are times I need a printer. For
instance-
PRINT and SHIFT-PRINT from the panel, LPRINT and variants
from a BASIC
program, a .CO that uses any of the printer rom routines such as
assembly listings from ZBGASM.CO <http://ZBGASM.CO> with /LP.
My printer (a DMP105) is probably broken beyond repair and I
can't get
ribbons for it anyway. This was my plan B:
I used a Arduino Nano clone (AliExpress $2-$3), a foot of 26
conductor
IDC ribbon cable, a crimp-on 2x13F and a USB jumper. The
2x13F goes in
the Model 100 printer port. The USB goes to a PC running a
terminal
program such as PuTTY. The Nano is in the middle and its sketch
(Arduino-speak for program) handles the handshake and
parallel to serial
conversion and yields a 9600b stream that's the serial
replica of the
M100 printer parallel output. On the PC the "printer" output
and be
viewed, scrolled, saved, and printed. Not quite the same as
a dot-impact
printer but quieter and faster and it doesn't need ribbons.
If anyone wants to give this project a try I can provide a
materials
list, a sketch listing, a wiring diagram, and pixs.
